IMPROVEMENT IN GAGlNG-RODS.

Specification forming part of Letters Patent No. 54,229, dated April 24, 1866.

To all whom fit may concern:

Be it known that I, W. J. TAIT, of Bergen, Hudson county, State of New Jersey, have in- 'vented a new and useful Improvement in Gaging-Rods; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure l is a vertical longitudinal section of a barrel through the bunghole, showing` my improved rod in position for reading the scale. Fig. 2 is a side view of my improved rod.

Similar letters of reference indicate like parts. t

My invention has for its object to furnish a gagng-rod which shall indicate to the gager the exact point at which to read off the scale, and it consists in combining with thordinary gaging-rod aslide-rod and stop, as hereinafter more fully described.

A represents an ordinary gaging-rod, constructed with ascale in the usual manner.

In usingrthe'old'gaging-rodftfter putting` it into the cask in the manner represented in Fig. l, it was necessary to determine with the eye the diagonal line across the rod where the plane ot' the lowersurfacc-9 the stave at the bung-hole would crosslthe rod. The position of this line is difficult to be determined with exactness in this Way, and so great is this difficulty that experienced and skillful gagers will frequently find a difference of a gallon or more between the results of two successive admeasureme'nts of the same cask.

To the edge ofthe rod A, I attach a sliding rod, B, by bands() and D, so that it may slide freely up and down the rod A. This rod is kept from sliding so far in either direction that the bands C and D would slip from the ends of the rod A by the pins or stops E and F. The band Ois made with one of its sides higher than the other,so that its upper edge may cross the edge of the rod A obliquely, as represented by dotted lines in IFig. 1, in about the line in which the plane of the lower surface of the stave of the cask at the bung-hole would cross the rod, so as not to interfere with reading the scale when using the rod.

To the opposite sident'. the rod A from the yrod B there is pivoted a stop, G, having arms of unequal length. The upper edge of this stop should be curved to about the curve of the staves of the ordinary cask, in gaging which the rod is to be used.

In using my improved rod it is inserted in the cask in the ordinary manner, as represented in Fig. l. The slide-rod B is then d rawn up, care heilig taken to guide the stop G so' that it may take the position represented in Fig. l and the result read from .the scale. The rod is then turned and `the otherend of the cask gaged in the same way. One arm of the stop G may be made heavier than the other or weighted, so as to takethe required position automatically but l prefer to make it uniform Iand guide it into position, as before described.

I claim as new and desire to secure by Letters Patent- An improved gaging-rod formed by conibining the slide-rod B and stop G with the ordinary gaging-rod, substantially as described, and for the purpose set forth.
